Substitute Part Grouping Explanation

The substitute component identified for the SN320002NSR is the LM2902DR, manufactured by Rohm Semiconductor. Substitution compatibility is determined by the following criteria:

Substitution Basis:

• RoHS3 Compliance: Both parts meet ROHS3 compliance requirements
• Moisture Sensitivity Level: Both parts rated MSL 1 (Unlimited)
• Functional Category: Linear amplifier integrated circuit
• Package Type: Surface mount configuration (14-SOIC/14-SOPJ)

The LM2902DR is a general-purpose operational amplifier with 4 circuits in a 14-pin SOIC package, providing electrical and mechanical compatibility for applications requiring the SN320002NSR.

Parameter Comparison

Engineering Selection Recommendations

Selection between SN320002NSR and LM2902DR should be based on the following factors:

For SN320002NSR:

• Preferred when original Texas Instruments sourcing is required
• Limited availability due to Last Time Buy status; current inventory of 852 units available
• ROHS3 compliance and MSL 1 rating suitable for standard storage and handling conditions

For LM2902DR:

• Suitable as substitute when supply of SN320002NSR becomes unavailable
• Significantly higher inventory availability (90223 units in stock) ensures supply continuity
• ROHS3 compliance and MSL 1 rating maintain equivalent environmental and handling specifications
• Note: LM2902DR carries Obsolete product status; long-term availability should be evaluated

Both components meet identical compliance and moisture sensitivity requirements, enabling functional substitution based on application requirements and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can LM2902DR directly replace SN320002NSR in production?

A: LM2902DR is identified as an equivalent substitute based on RoHS3 compliance, MSL 1 rating, and surface mount packaging compatibility. Functional compatibility depends on circuit-specific requirements not detailed in the component specifications provided.

Q: What is the significance of Last Time Buy status for SN320002NSR?

A: Last Time Buy status indicates that Texas Instruments will no longer manufacture this part after current inventory is depleted. This necessitates identification of substitute components for future production requirements.

Q: Are there differences in package specifications between these parts?

A: SN320002NSR package specifications are not provided in available documentation. LM2902DR is specified as 14-SOIC (0.154", 3.90mm Width) surface mount package. Package compatibility must be confirmed for specific applications.

Q: How do the inventory levels affect component selection?

A: SN320002NSR has 852 units currently in stock, while LM2902DR has 90223 units available. For immediate requirements, SN320002NSR inventory is limited. LM2902DR provides significantly higher availability for sustained production needs.

Q: What compliance certifications apply to both components?

A: Both SN320002NSR and LM2902DR are ROHS3 compliant and rated MSL 1 (Unlimited moisture sensitivity). These certifications ensure equivalent environmental and handling compliance for applications requiring these standards.

Q: Is LM2902DR's Obsolete status a concern for substitution?

A: LM2902DR carries Obsolete product status, indicating it is no longer in active production. While currently available in inventory, long-term supply availability should be evaluated for applications requiring extended component sourcing periods.
